What’s a Cardiac Device?
If you have a heart arrhythmia, your doctor may decide you need a cardiac device to correct your irregular heartbeat. A cardiac device is usually considered when other treatments do not work.
Your doctor will surgically insert a small electrical device, such as a pacemaker, under the skin of your chest or abdomen. This device sends electrical pulses to restore normal heart rhythm.
Types of Cardiac Devices
Your cardiac device may be a:
- Pacemaker – Small, wireless device attached to the heart to control a slow heartbeat and keep it beating at a normal rate
- Biventricular pacemaker – Pacemaker with a third wire to send impulses to the heart to synchronize the lower-left chambers (ventricles)
- Implantable cardioverter defibrillator (ICD) – Device that delivers an electrical impulse to return a fast heartbeat (ventricular arrhythmia) to a regular heartbeat
- Loop recorder – Wireless cardiac device that records your heart rhythm
